Article

Summary

DevelopingBufo arenarum embryos were treated during gastrulation with cadmium chloride in concentrations ranging from 6×10−7 to 1.5×10−5 M Cd++ at 20 and 30°C. Initial failures at gastrulation result mainly in axial incurvations, microcephaly, hydropsy and abnormal tail formation. The higher temperature has a dual effect: at high concentrations of Cd early malformations are significantly increased, whereas at low concentrations the higher temperature prevents alterations.
